/cgl/ - Cosplay & EGL

Is is possible to do the younger look in larme while fully covering the areas in gray? (meaning no wide necklines or cutouts there) (excuse the crappy drawing but it was easier than trying to explain with words)
I'm extremely uncomfortable showing off my back, it's full of acne scars, or wearing anything that emphasizes my breasts, meaning no cleavage, no low necklines, no underbust straps (high waist is fine), no fitted/padded cups, etc
I have no problem exposing anything outside of that zone though (arms, legs, midriff, etc), so can covered on top/exposed on the bottom work and look balanced?
